Patent JP-H0993222-A (JP)
Title: Optical communication equipment and wavelength control method
Inventor: KUBOTA OICHI
IPC: H04B10/516
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To easily secure an idle area by identifying a transmitted signal detected through the use of an optical transmitter to be a signal from an optical source of its own station when its wavelength is coincident with a wavelength of an output of a wavelength variable light source and to be a signal from other terminal station when the wavelength is coincident with a wavelength of a transmission light from other terminal station. SOLUTION: An optical transmitter of each terminal station uses an optical filter 5 built in the optical transmitter to detect a wavelength region transmitted in a system and to keep wavelength interval with an adjacent wavelength in the wavelength arrangement. When a transmitted wavelength λf of the filter 5 is swept out and the λf is coincident with a wavelength λf1 of the output light of a wavelength variable light source 1, an identification device 6b outputs an identification signal and when the λf is coincident with any of wavelength sets of other terminal station, an identification device 6a outputs an identification signal. When the other terminal station on a transmission line makes transmission by wavelength sets λa, λb, λc.  A wavelength variable light source 1 of its own terminal station is going to start transmission by a wavelength λ1. Even when the wavelength λ1 of the light source output approaches any of wavelength sets of transmission lights of other terminal station because the optical paths are different, the both are distinguished.

Title: Conveying roller and long material conveying method using the same
Inventor: IHASHI NORITAKA
IPC: B65H23/025
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a conveying roller not affected by the environmental condition such as a temperature or the like, and capable of dispensing with the accuracy in rolling work and mounting, and preventing the wrinkling on the conveyed paper with low cost and small efforts by making surfaces of both ends of a conveying roller out of a material having a small coefficient of friction in comparison with that of a surface of its central part. SOLUTION: This conveying roller 1 has the different coefficients of friction between both end surfaces 2a, 2b and a central surface 3. The wrinkling is easily produced on both ends in the width direction of a long material when the long material such as the paper to be conveyed, made of a thin, soft and wide resin film or the like is conveyed. To eliminate the wrinkling and to make both ends of the long material slippery, a coefficient of friction of both end surfaces 2a, 2b of the conveying roller 1 is relatively lowered in comparison with that of a central surface 3, for example, with the difference of approximately 0.1. Both end surfaces 2a, 2b are made of, for example, rubber, and the central surface 3 is made of, for example, stainless. Whereby the long material can be easily and surely prevented from being wrinkled.

Abstract: PURPOSE:To feed back even a signal without delay by providing a feedback loop which delays a signal by an hourly amount shorter than one sampling period and obtaining an output signal after a signal circulates in the feedback loop several times during one sampling period. CONSTITUTION:A signal is inputted from an input terminal 105 during the sampling period, gets in an output terminal 107 through an adder circuit 106 and led to a nonlinear high pass filter 2. After a D-flip flop 108 for bits composing a signal which is operated by a delay clock 109 with a frequency N-times a sampling frequency delays the signal obtained in the filter 2 by 1/N one sampling period, the signal is fed back to another input terminal of the adder circuit 106. The titled filter is constituted so that the signal circulates in the feedback loop N-times during one sampling period. Thus the circulating type digital filter is attainable which provides results similar to a case where a signal circultates without delay.
